MACHINE FOR CLEANING INTESTINES.

SPECIFICATION forming part of Letters Patent No. 363,370, dated May 24:.1887.

Application filed October 5, 1886. Serial No. 215,392. (No model.)

To all whom it may concern;

Be it known that we, FERDINAND E. Davis, residing at Englewood, Cookcounty, State of Illinois, and OSCAR ABERLE, residing at Chicago, in thecounty of Cook and State of Illinois, and citizens of the United States,have invented a new and useful Improvement in Machines for CleaningIntestines, of which the following is a full description, referencebeing had to the accompanying drawings, in which Figure 1 is a plan.Fig. 2 is a side elevation. Fig. 3 is a detail showing the devices fordriving the reel from the main shaft. Fig. 4 is an end View. Fig. 5 isan end view of the reel. Fig. 6 is a vertical section of the. reel. Fig.7 is a detail showing one of the eccentric levers used for holding thesliding frame in place. Fig. 8 is a plan of the main frame, somewhatreduced in size. Fig. 9 is a vertical section of one of the brushes.Fig. 10 is a detail, being a section at line 00 w of Fig. 1. The housingis not shown in Figs. 2 and 4. This machine is primarily designed to beused in cleaning beef-intestines to prepare them for various commercialuses. The machine may also be used for cleaning tripe and some otheranimal products.

The invention consists in the construction and combination of parts, ashereinafter more fully set forth and claimed.

In the drawings, A represents the main frame.

13 is a portion of the main frame somewhat elevated, as shown, above theother parts.

0 O are two armsor supports extending out from B.

a, Fig. 8, are slots in the arms 0 O, and in the raised portion 13 ofthe frame A.

b are ways projecting upward from that part of the main frame marked B,and from the arms O O.

D is a bar which rests upon the ways I), the bar being provided withgrooves, into which the ways enter, and with downward projections, a.

E is a shaft supportedin bearings in the posts F, which extend upwardfrom the bar D.

G is a brush on the shaft E.

c is a fixed pulley on the shaft E.

The bar D is held in place by bolts (Z, which pass through two of theslots a, and by the eccentric levers e, which are pivoted in the lowerends of the bolts d.

f is a screw, provided with a hand-wheel, g, by means of which thesliding bar D can be adjusted.

I-I, Figs. 2 and 10, is another sliding bar corresponding with D.corresponding with b.

E is another shaft-supported in bearings in posts F, which projectupward from thebar II.

c is a fixed pulley on the shaft E.

G is a second brush on the shaft E.

The bar H may be held in place by bolts and eccentric-levers, asdescribed for the bar D.

I I are housings or guards over the two brushes, the lower ends of whichhousings are,

It rests upon ways as shown, secured one to each of the bars D i H. (SeeFig. 10.)

J, Figs. 1 and 10, is asmall roller supported in bearings secured to thehousing 1.

The construction of the brushes is shown in Fig. 9, in which it is ahead which is keyed to the shaft E. z is a collar upon the shaft E,thecollar being screw-threaded. j is a head having a central opeuing vhichis screw-threaded to correspond with the screw-thread upon the collar 6.Theheads hj are each provided with a notched groove, 70, on the inside,which groove is cut into the heads at an angle. Z is a suitablecylinder, to which the brush material at is so cured in any knownmanner. The cylinder Z is of such size that its ends enter the grooves7; in

the heads h j, and by turning the head j the cylinder can be clamped inplace between the two heads h j, andwill be securely held. The brushmaterial may be rice-roots, Russian bristles, palmetto, or other knownsuitable substance. The brushes revolve in opposite directions, asindicated by arrows in Fig. 2, and the screw-threads upon the collard onone shaft are to be right-handed and on the other left-handed.

K is a driving-shaft supported in bearings on the main frame.

L L are two pulleys, one of which is loose, and the other is a fixeddrivingpulley driven by a belt which is not shown. a

M is a shaft, one end of which carries a reel, N, which, as shown, iscollapsible. a isahead at one end of the reel. are bars, each of whichis pivoted at one end to the head a. p is a sliding hub on the shaft M.

q are rods. One end of each rod is pivoted to the outer end of a bar, 0,and the other end of each rod is pivoted to the hub 10. (See Figs.

' 1, 5, and 6.) Each of the bars 0 isprovided on one edge with devicesfor holding one end of the intestines. Three forms are shown, one ofwhich are notches r. Springs 1" are another form. Small hooks 7" are thethird form.

8 is a worm-screw on the shaft K, which engages with a worm-wheel, t, onone end of a shaft, 20, supported in suitable bearings. The other end ofthe shaft 20 carries a beveled gearwheel, '0, which engages with anotherbeveled gear-wheel, w, on the reel-shaft M,and by these devices thereel-shaft is driven from the main shaft K.

O is a large sprocket-wheel on the shaft K.

P is a small sprocket-wheel on a shaft, Q, which is supported inbearings at the upper ends of standards R, which are secured to theframe.

S is a driving-pulley on the shaft Q.

T is a belt which drives the shaft E.

U is a belt which is crossed, and drives the shaft E.

V is a chain on the sprocket-wheels O 1?.

The operation is as follows: One end of each intestine which is to becleaned is to be passed in between the brushes, which can be readilydone from their outer ends, there being an opening between the arms 0 Oand the brushes, as shown in Figs. 8 and 10. The intestine is to becarried up over theroller J by the operator to thereel N, where one endmay be passed to one of the holding devices on one of the bars 0, andthe machine being in motion the movement of the reel will gradually drawthe intestine between the two brushes, which, being in rapid motion,will thoroughly clean the intestines. When the reel is full the machineis to be stopped, the hub 19 can be moved in or out a little on theshaft M, and the parts '0 q, being hinged,-as aforesaid, the reel willpartially collapse, and then the clean intestines on the reel can beeasily removed. The parts of the reel can then be returned to theirformer position ready for use again. The driving-pulley L may have abouteighty revolutions per minute, which'will give about two revolutions perminute to the reel and about sixteen hundred revolutions per miuute tothe brushes. The shaft Q is driven by the chain V, which runs upon thesprocket-wheels O P.

The distance of the brushes from each other can be adjusted by movingthe bar D, which can be done by loosening the eccentric levers c, andthen turning the screw f. We have not shown a screwvfor moving the barH; but one may be provided, if desired.

It may be stated that cleaning beef-intestines consists chiefly inremoving the mucous lining of the intestines. We do not limit ourmachine and devices to the single use of cleaning beef-intestines.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a machine for cleaning intestines, the combination of a pair ofrotary brushes, one of which is adjustable to and from the other, andbrush-supports open at one end to facilitate the insertion of intestinesbetween said brushes, substantially as described.

2. The combination of the arms 0 O', h aving ways I) b, the bars D H,and the rotary brushes G G, said brushes being mounted on shaftssupported in bearings on the bars D H, and one of said bars beingadjustable to vary the distance between the brushes, substantially asdescribed.

3. The combination, with the rotary brushes G G and brush-supports openat one end to facilitate the insertion of intestines between saidbrushes, of a collapsible reel for receivting the cleaned intestinesfrom the brushes,

substantially as described. r

4. The combination, with the rotary brushes G G, of the shaft M, and acollapsible reel mounted 011 said-shaft and composed of the head n, thebars 0, pivoted in said shaft and provided with devices for holding oneend of the intestines, the sliding hub 10, and rods q, pivotallyconnected with said bars and hub, substantially as described.

5. The combination of the frame A, having raised portion 13 and arms 0O, the bars D H, one or both adjustable on said arms, the brushshafts EE, journaledin bearings on said bars, and carrying brushes G G andpulleys c c, the shaft M, carryinga collapsible reel, the driving-shaftK, having sprocket-wheel O, the shaft Q, having sprocketwheel 1? andpulley S, the chain V, belts TU, and gearing for connecting the shafts KM, substantially as described.
